Lower Case and Title Problem

Hi guys,

I have Catch Everest (free) theme. Thanks for theme. It is really good.

I have these codes below and my problem is cannot make menu letter “lowercase” and in browser there is no title. Only ” | ” there is this. Actually, there should be the site name.

Thanks for the answer in advance

#hgroup-wrap, #site-logo { padding: 0; }
#masthead { background-color: #E0E0E0; }

/* For menu bar color – general */
#header-menu {
background-color: #C8C8C8;

/* For menu bar color – hover color */
#header-menu ul.menu li:hover > a,
#header-menu ul.menu a:focus {
